Answer:

18 : 26

Step-by-step explanation:

It is very easy, angel fish and clown fish are fish, so once you add them up you get 26. The seahorses are 18 and we are supposed to make them S:F. Therefore you put the seahorses first and the fish second, so you get the answer 18:26

Answer:

Step-by-step explanation:

Supplement of 123° = 180°-123° = 57°

x = 180-57-80 = 43°

Answer:

Step-by-step explanation:

2(3x+2) + x = 39

6x+4+x = 39

7x = 35

x = 5

Answer:

$13,400

Step-by-step explanation:

Simple Interest = principal × rate × time

principal= $9000

Rate= 12/100=0•12

Time=5years

Simple interest =PRT

= 9000× 0•12 × 5

= 5400

Total amount to be paid = 9000 + 5400

= $13400

Answer:

16

Step-by-step explanation:

3x-8=2x

x=8

QR=2*8=16

Answer:-8

Step-by-step explanation:

The data represent a linear function because there is a common difference of -9.

The term linear function refers to two distinct but related notions: In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one.

Given, the table, we need to see whether the data in the table represent a linear function or an exponential function.

From the table, we have the following highlight :-

As the values of x increase by 1, the values of y decrease by 9

A decrement of 9, means -9

This means that, the common difference is -9.

Only a linear function can have a common difference.

Hence, the true statement is (b)

Answer:

14. T = 20 + 1.50d so T = 44, 15. p = 1.25s - 135 must sell 109 to make a profit

Step-by-step explanation:

14. T = 20 + 1.50d so for 16 deliveries T = 20 + 1.50(16) , T = 44

15. p = 1.25s - 135 so if they sell 109 items (s) there is a profit since the profit starts after the original cost is recovered

Answer:

so you're adding up all the numbers together so 16+13+20+16+12+17+18=112

then you are dividing it by how many numbers there are so there are 7 numbers in total 112÷7=16

Please mark me as brainliest. thanks!!!

Answer:

is it this one?

Step-by-step explanation:

Answer:

The slope is 5/4 and the y-intercept is 2.

Step-by-step explanation:

5x-4y=-8

4y=5x-(-8)

4y=5x+8

y=5/4x+8/4

y=5/4x+2

y=mx+b where m=slope and b=y-intercept.

Answer:

2

Step-by-step explanation:

Use the vertex form equation first since you are given the vertex (-1,-2) where you have (h,k) so h = -1 and k = -2

y =  [tex]a (x - -1)^{2}[/tex] + (-2) so if you simplify we get y =  a(x+1)^2 -2

Since we are also given a point we can solve for a so x = 2 and y = 16

16 = a(2+1)^2 - 2

16 = a(3)^2 - 2

18 = 9a

a = 2

Answer:

(2,114)

Step-by-step explanation:

g(x)= -16x² + 64x + 80

Plug 2 in to check if it's correct.

g(2)= -16(2)² + 64(2) + 80

-16(4)+128+80

-64+128+80

= 144

Answer:

144

Answer:a)757liters

b)1, 713 litres

Step-by-step explanation:

Amount of water used on Monday =1,235l

Amount of water used on Tuesday =478liters

Difference in volumes for the two days

=1,235l -478l

=757liters.

Total amount of water used up in Total

1,235litres +478liters

=. 1, 713 litres.

Answer:

25 questions

Step-by-step explanation:

20 questions = 80%  If she got 80%, that means she got 20 questions correct.

5 questions = 20%  Here, we simply just divide by 4 to give us 20%.

25 questions = 100%  The total of the test would of course equal 100%, so we just multiply by 5 to give the total questions.

I hope this helps you!! ^-^

Answer:

25.

Step-by-step explanation:

By proportion it is

(100/80) * 20

= 1.25 * 20

= 25.

Answer:

Step-by-step explanation:

cost = 3 pitchers × $0.50/pitcher = $1.50

revenue = 36 cups × $0.15/cup = $5.40

profit = $5.40 - $1.50 = $3.90

Answer:

YZ = 14

Step-by-step explanation:

We are told that;

WZ = 23 and XZ = 18

Now, ∠X in △XWZ which is a right angle triangle can be gotten using trigonometric ratio.

Thus;

WZ/XZ = tan θ

23/18 = tan θ

tan θ = 1.2778

θ = tan^(-1) 1.2778

θ = 51.95°

Now, the ∠X is 90° in △XWY.

Thus, in △XZY, ∠X = 90 - 51.95 = 38.05°

Again, using trigonometric ratio, we can find YZ.

Thus;

YZ/XZ = tan 38.05°

YZ = XZ tan 38.05°

YZ = 18 × 0.7827

YZ = 14.0886

Approximating to a whole number gives: YZ = 14

Answer:

18 seconds

Step-by-step explanation:

convert km/h to m/s and you get 22.22m/s. Then divide 400 by 22.22 and the answer is 18 seconds.

Answer:

y = 1/2x + 3

Step-by-step explanation:

Rise/Run and since y = 3 when x = 0, then the b part in y = mx + b is 3.
